Russell Crowe has lost over 16lbs on a tough new exercise and diet regime.

The Oscar-winning actor – whose weight has fluctuated over the years – began a 105 day bid to get into shape on June 17 and has already ditched some of his excess flab by following a gluten free diet and a punishing fitness schedule.

Writing on his twitter page today (13.07.11), he revealed: “220 lbs this morning, started at 236.4 lbs. 45 min walk, 12 mins eliptical, weighted objects 40 mins, walk 25 mins. 2400 cal a day maximum, all meals & all beverages. Where possible gluten free (sic).”

Since announcing his get fit plan, Russell has been posting regular updates for his 253,289 twitter followers, writing last month: “day 12 of a 105 day training period, there is a long way to go, one layer of tissue paper per day of effort and diet … it takes a long time (sic).”

Dad-of two Russell – who is married to singer Danielle Spencer – is hoping to lose a total of 41.1 lbs, tweeting “ My goal around 185 lb started at 236.4 (sic)”
